iOS 10.2 Jailbreak And Why You Should Save SHSH2 Blobs Right Now

Could there be a possibility of an iOS 10.2 jailbreak making its way into the public domain sooner rather than later? The current Yalu + Mach_Portal jailbreak, which liberates select 64-bit devices running iOS 10.0.x to 10.1.1 from Apple’s walled garden, is still very much in beta, and thus recommended for advanced users and developers only.

And now with iOS 10.2.1 release on the horizon, a series of tweets from Luca Todesco recommends those interested in jailbreaking to save SHSH2 blobs for iOS 10.2 right now in case an iOS 10.2 jailbreak does show up in future.

Italian developer and security researcher Luca Todesco has been involved in the jailbreak community for as long as we can remember in one form or another. In the last twelve months or so, he has managed to propel himself into being one of the most prominent members of the community through his tiresome work and dedication to finding vulnerabilities and bugs in iOS that can be exploited to produce functioning jailbreaks for Apple’s mobile devices.

His latest work is there for all to see with the release of Yalu + Mach_Portal for iOS 10.0.x – 10.1.1, but recent tweets from him have raised excitement up for a future jailbreak on iOS 10.2.

Suggestion: keep 10.1/10.2 blobs real close on pre7 64 bit.

This obviously sparked a discussion about whether or not he knew something the rest didn’t about the potential of an iOS 10.2 jailbreak. Another tweet from him however has played down the excitement about the jailbreak at the same time as actually fueling the speculation fire:

A jailbreak for 10.2 is not planned, but it is still vulnerable to the underlying technique used, so it’s the second best fw.

He has went on to further clarify that in couple of more tweets:

10.2 is vuln to my KPP thing. Not blowing 0days for it 😉

By that I imply that KPP alone is not enough: I am not supplying any other missing part.

What we can deduce from all this is that the KPP technique Luca used in current Yalu + Mach_Portal jailbreak for iOS 10.0.x to 10.1.1 is still vulnerable in iOS 10.2, but that alone isn’t enough to achieve the full jailbreak in iOS 10.2. And while he has undisclosed 0days, which when combined with his already public KPP, can supposedly produce full jailbreak on iOS 10.2, he doesn’t want to blow it away for another public jailbreak.

The likely good news here is that someone else, like the Pangu Team, can pick up on his progress made on iOS 10.2 to hopefully produce a fully functionality public jailbreak.

It’s a long shot, yes, but there’s some progress made there already and hopefully it’s only a matter of time before someone picks up on the work he has left off on iOS 10.2 to create a full jailbreak. The current iOS 10.0.x – 10.1.1 jailbreak happened the same way as well after a member of Google’s Project Zero team released the exploit for iOS 10.1.1, which Luca combined it with his KPP to produce Yalu + Mach_Portal jailbreak for iPhone 7 and other devices.

We have seen it happen in the past, so it can happen again. And so like Luca, we will suggest all those who care about jailbreaking to save their SHSH2 blobs for iOS 10.2 right now while Apple is still signing it so that they can downgrade or upgrade to the firmware using Prometheus whenever a jailbreak for it is available, even if Apple ends up patching it in iOS 10.2.1 or later firmwares.

I wouldn’t say he’s a dick. He did release an exploit for 9.3, which is why a jailbreak for that even exists. And now he’s released his own jailbreak for 10.1. He also has an 0day that he’s holding on to, when he could sell it to Zerodium for $1.5 million. So it seems he plans to stick around the scene for awhile, otherwise, why not cash out and continue to do research?

I dont see no details. Could you please explain. Thanks

Jason

It’s a fake, it’s a scammer, beware!

Kelvin Guerrero

Does anybody jailbreak anymore???

Payton Sliepka

So we shouldn’t expect a jailbreak for iP7 10.2?

Eric Tan

I’m on 8.1.2, do I need to save my blobs as well? Or as long as I want to continue jailbreak, saving the blobs is a must?

ggbf

I’m on 9.3.3 on iphone 6splus and jailbroken (semi) should I upgrade to 10.2 and wait? The process of saving blobs is a bit of work, not sure if I can do it properly.

DontBeNosey

Call that a jailbreak? Its a mess.

SHSH2 Blobs can be saved for iOS versions which are still being signed by Apple. You cannot save blobs for older unsigned versions. If you save blobs for 10.2 it will help you downgrade to 10.2 when you have updated your iOS version. This is helpful if 10.2 jailbreak is released in future.
Simply put you can only upgrade or downgrade to unsigned iOS versions for which you have saved blobs. Like you cannot downgrade to iOS 10.1 from 10.3 if you don’t have saved blobs for 10.1

Darkshifter

what about 32 bit idevices? do we get to save blobs for older ios upto 9? and Apple TV3 JB?

Sumsoft

You can save blobs while Apple is signing the iOS. At the moment apple is not signing anything below 10.2 on iPhone.

Ali Mari Baloch

So i am on 10.0.2 on iPhone 7, do i need to upgrade to 10.2 to save my blobs?

SeekTruth

^ what he/she said.

Marty McFly

Even if it is a mess (which imo it isn’t) it’s still a jailbreak. If you’re not happy with it I have a couple of suggestions:

1-Learn to jailbreak/fix it yourself
2-Move to android
3-Get over it.

Darkshifter

yeah but there was an article saying older ios blobs could be saved for 64bit devices even though apple isnt signing them

Simon

I want to update to iOS 10, but currently on 9.3.3 semi-tethered JB. What are my options? Because normally I wait til there is a jailbreak release on the lastest firmware, but apple releases the next iOS update quickly to patch the jailbreakable firmware and stop signing it.

John J1101

if you haven’t DO NOT UPGRADE! 10.1.1 and older, use TSSSaver dont update though
